宽带网络接入方式的分析

The analysis of the connecting methods of the broad net

从实用的角度来看 ,目前对于家庭用户以及部分小企业来说 ,最实际和最合算的接入方式恐怕是ISDN和ADSL了。前者作为一种过渡方式 ,还是能从一定程度上解决Modem传输率慢的痼疾 ,同时也不是很贵。而ADSL作为目前比较先进的接入方式。将逐渐成为国内宽带接入的主流。虽然CableModem上网目前还会因高昂的费用无法得到更大范围内的普及 ,但其发展前景 ,特别是光纤传输方式无疑是宽接入最终的方向。至于STB顶盒上网 ,的确只是为目前打算用电视机上网的用户而准备的 ,还是期待它成熟的替代品出现的好。

From the practical point of view the most practical and economic connecting methods so far have teen ISDN and ADSL for family and some of the small enterprises. The previous one overcomes the shortcoming of slowness of Modem and is not expensive. While the latter will gradually become the main trend as a comparatively advanced method. Although the cable Modem can not be used in a large scale because of its expenditure, its prospects are bright especially for the method of the fibre transportation. STB, which is literally designed only for the users that plan to be on line through the TV set, will meet its better substitute.
